产品概述
The ADM690A series Supervisory Circuit offers complete single chip solutions for power supply monitoring and battery control functions in microprocessor systems. These functions include µP reset, backup battery switchover, watchdog timer and power failure warning. On the ADM690A/ADM802L/ADM805L the reset voltage threshold is 4.65V. The family of product is fabricated using an advanced epitaxial CMOS process combining low power consumption and high reliability. RESET assertion is guaranteed with VCC as low as 1V. They provide a pin-compatible upgrade for the MAX690A/MAX692A/MAX802L/MAX802M/MAX805L.
- Automatic battery backup power switching
- Voltage monitor for power-fail
- Reset assertion down to 1V VCC
- 1.6s Watchdog timer
- 100µA Quiescent supply current
